The chuck has been discussed here before. I don't have one and don't think I will and it isn't because of some flaw but rather just something I don't need since the wrenches do fine for me.

The composite pins aren't new and I have thought about getting a gun to shoot them for purposes like he showed. I have on on my list but who knows if I will ever actually get one.
The shop vac cart hose real is interesting in that it is for the smaller hoses, if that is what you use I guess it might be OK but I'd like to see one for the 2+ hoses that I use most. Also I don't have a lot of attachments for my vacs, in fact I don't have any. What I do have is the dust deputy, wonder of they will address that need.
He is not one I watch much but only occasionally which is a step above rare in my you tube viewing.
